Lady fern spores
by David Thomas
Recently I started looking at the underside of fern fronds, knowing only vaguely that spores often form there. Here is my first image worth posting, hopefully an example of my vision for macros, "Seeing the Unseen." I picked a small section of this frond and viewed it on a black background.
On the screen, the image is about 5 to 6 times actual size, resulting from my Canon 7D, 90mm macro lens with 1.4X extender, and about a 50% crop (on purpose for additional magnification).
The red elongated granular areas are called "sori" (plural of sorus), which are collections of tiny "sporangia," each of which contains many even smaller spores. Seeing the sori is easy by eye (although you still have to look under the leaflets to find them), but the finer details are hard to see without magnification.
Comments and criticisms welcome, thanks,

4 commentsI like the choice of subject a lot. I agree that you are seeing the unseen.
I think there are improvements that could make this image better. You don't mention the lighting, but the strong front light and hard shadows are not flattering. I've made some photographs of ferns that I really like by finding strong back light, then bouncing fill back in. I tend to use natural light and a reflector, but I've seen examples of folks backlighting with flash and bouncing back to fill.
I think the main stem is a really powerful element in the photo. To me, it needs to be either given complete dominance in the frame, or made weaker. That's an "art" discussion that has no real answer. I mentioned the heart of the photo already. I like the idea of showing us something we don't often, or ever, see.
Finally, it is impossible to tell from a jpeg on a monitor, but it you may have been a little over ambitious in magnification. It could also be a basic technique error (missed focus for example) but I doubt it. It is pretty clear (unclear) in the larger version that it isn't sharp throughout, which I imagine was the goal.
I hope this is helpful not discouraging,
